Can a Self-Help website beat group therapy for binge eating?
NCT ID NCT05873127
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested two ways to deliver cognitive behavioral therapy (CBT) for binge eating: a web-based self-help program and online group therapy. 120 adults with bulimia or binge eating disorder took part. The goal was to see which approach better reduces binge eating episodes and improves impulse control.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Enhanced Cognitive Behavioral Therapy (CBT-E) delivered via web-based guided self-help or online group sessions
- What this could lead to
- If successful, this could show that a low-cost, self-guided online program works as well as group therapy for reducing binge eating, making treatment more accessible.
- What could go wrong
- This is a small, completed study in China with 120 participants, so results may not apply to other populations. Both treatments are behavioral, not medical, so benefits may be modest and not sustained long-term.
